What network ports does rpc.statd use?

Issue

• rpc.statd is using a random port number in addition to the port number that it is configured to listen on. Why?
• rpc.statd is listening on all the interfaces, why?

[root@test]# grep PORT /etc/sysconfig/nfs
RQUOTAD_PORT=875
LOCKD_TCPPORT=32769
LOCKD_UDPPORT=32769
MOUNTD_PORT=892
STATD_PORT=662
STATD_OUTGOING_PORT=2020
#RDMA_PORT=20049

[root@test ~]# netstat -nlpu | grep rpc.statd
